Ball Screws and Nut Assemblies
DINGS’ MOTION USA
Ball Screws for High Precision & High Efficiency Linear Motion
DINGS’ Motion USA provides precision ball screw and nut assemblies designed for smooth, efficient, and highly repeatable linear motion across robotics, laboratory automation, medical devices, semiconductor equipment, and industrial systems. Each assembly is engineered with optimized ball recirculation, controlled lead accuracy, and high load capacity to support demanding OEM applications.
Compared to traditional lead screw systems, ball screws deliver significantly higher efficiency, reduced backlash through preload, and improved positioning accuracy. These advantages make them well-suited for applications requiring consistent motion performance, higher speeds, and tighter control.
If you’re evaluating ball screws for your application or need help selecting the right configuration, our engineering team is available to assist.

Notes:
1. Effective stroke / screw length notation: Ex. 55R80 indicates an effective stroke of 55mm and a total screw length of 80 mm.
2. Acronym reference: FB1 = Flanged Single Nut Type 1, FB2 = Flanged Single Nut Type 2, CB = Cylindrical Single Nut, KB = Square Single Nut, MB = Metric Thread Single Nut.
3. Left-Hand thread option available on all C5 grade screws.
4. For rolled C7 ball screws, the shaft-end diameter must not exceed the root diameter of the screw.
5. For lengths exceeding the maximum production limit, please contact our sales engineers.
6. Dynamic and static load ratings are shown by nut type because load capacity varies by nut style for a given screw diameter and lead.
Ball screws are a strong fit when:
High positioning accuracy is required. Applications that depend on precise, repeatable motion benefit from the reduced backlash and improved lead accuracy that ball screws provide.
Efficiency and speed are critical. With rolling contact between the screw and nut, ball screws offer significantly higher mechanical efficiency than sliding lead screw systems, enabling higher speeds with less input torque.
Backlash must be minimized or eliminated. Preload options allow ball screws to operate with little to no axial play, improving system stiffness and overall motion control.
Higher loads or duty cycles are involved. Ball screws are well-suited for applications that require continuous operation, higher thrust, or extended service life under demanding conditions.
Smooth, low-friction motion is important. The rolling ball mechanism reduces friction and wear, resulting in quieter operation and more consistent performance over time.
If your application prioritizes cost sensitivity or operates under lower performance requirements, a lead screw solution may still be appropriate. However, when precision, efficiency, and long-term performance are critical, ball screws are often the better choice.
When to Use Ball Screws
Ball screws are typically selected when application requirements extend beyond what traditional lead screw systems can efficiently support. While lead screws remain a cost-effective solution for many applications, ball screws are better suited for systems that demand higher performance, tighter control, and long-term reliability.
